M is for... Moroks

A belligerent race of humanoids from the planet Morok. They wore white uniforms with broad shoulders, and had distinctive peaked hairstyles. 

The Moroks once had a huge empire, accomplished through war and invasion. One of the worlds they conquered was Xeros. The adult population was destroyed, but the younger generation were allowed to live and shipped off to act as slave labour on other planets when old enough to work. The Moroks later established a museum to celebrate their conquests on Xeros. It even included a Dalek from Skaro.

Over time, the empire began to decline. Governor Lobos, custodian of the museum, bemoaned the fact that his people no longer had the appetite for war. He found himself commanding a military outpost facing poor morale, and an attraction which no-one visited anymore.

When the TARDIS arrived on Xeros he saw it as an opportunity to add to the collection, and perhaps reignite some interest in the museum. The Doctor's arrival, accompanied by Ian, Barbara and Vicki, coincided with a growing rebel movement among the Xeron youth - led by Tor.

The one thing they lacked was weaponry. There was a well-stocked arsenal on Xeros, but it was protected by a complex computer sentinel. Vicki was able to show Tor and his  friends how to bypass this. Lobos subjected the Doctor to a freezing process so that he could be turned into an exhibit, but he was rescued by Ian.

The Xeron revolt took place and proved successful. Lobos and his commander were killed in the battle, and the surviving Moroks expelled - their museum rapidly dismantled.
